HARRY E. GOLDEN, 0F DUNBAR, PENNSYLVANIA.

INDICATOR.

To all whom it may concern:

Be it known that I, HARRY E. GOLDEN, a citizen of the United States ofAmerica, residing at Dunbar, in the county of Fayette and State ofPennsylvania, have invented certain new and useful Improvements inIndicators, of which the following is a specification, reference beinghad therein to the accompanying drawing.

This invention relates to a closed register ing indicator, for thehoisting engines of mine shafts, slips, wells and similar subways.

The primary object of my invention is the provision of positive andreliable means in connection with a hoisting cable for quicklydetermining the location of a trip or elevator in a shaft or flatleading therefrom.

Another object of my invention is to provide an alarm in connection witha hoisting engine for producing an audible signal previous to a tripreaching its destination, whereby the engineer or operator of thehoisting engine can give the engine his immediate attention.

A further object of my invention is to provide a simple, durable andinexpensive indicator for designating the distance a trip travels in ashaft and then the distance traveled by the trip in a flat.

Vith the above and other objects in view which will more readily appearas the invention is better understood, the same consists in the novelconstruction, combination and arrangement of parts to be presentlydescribed and claimed.

Referring to the drawings :Figure 1 is a front elevation of my indicatorwith the dial thereof broken away to show a portion of the interiormechanism, and Fig. 2 is a vertical sectional view of the same.

In the accompanying drawings, 1 designates a cylindrical casing having aclosed dial 2 which is held upon the casing by a rim 3 threaded thereon.Extending vertically through the center of the casing is a support 4provided with brackets 5 for supporting a plate 6.

Journaled in the support 4: and the plate 6 is a shaft 7 extendingthrough the rear wall of the casing 1. The protruding end of the shaft 7is adapted to be connected to the driven shaft 7 of the hoisting engineby meshing gear wheels 8. Mounted upon the contracted end 9 of the shaft7 is a long Specification of Letters Patent.

hand 10, the purpose of which will presently appear.

Mounted upon the shaft 7 adjacent to the support 4 is a small gear wheel11 meshing with a large gear wheel 12 mounted upon a revoluble shaft 13journaled in the support a and the plate 6. Mounted upon the shaft 13 isa small pinion 1A meshing with a large gear wheel 15, mounted upon asleeve 16, revolubly mounted upon the shaft 7 between the small gearwheel 11 and the contracted end 9 of said shaft. The forward end of thesleeve is provided with a short hand 17.

Secured to the sleeve 16 in front of the plate 6 is a disk 18 having aplurality of cireumfercntially arranged openings 19 adapted to receive aplug 20. The plug 20 is adapted to impinge a pivoted pawl 21, carried bythe plate (5, and this pivoted pawl is adapted to strike a resilient arm22 and move said arm into engagement with a contact 23, carried by theplate 6 and insulated therefrom as clearly shown in Fig. 2. Theresilient arm 22 is connected to a wire 24, while the contact a3 isconnected to the wire These wires are adapted to connect with anelectric bell 26 and a suitable source of electrical energy, as abattery 27, said bell and said source of electrical energy beingconnected by a wire 26 Upon the dial are circumferentially arrangednumerals from 1 to 16 and the hand 10 is adapted to make one revolutionwhile the hand 17 is moving from the nume al 1 to the numeral 2.

In order that the operation of my invention can be fully understood, theindicator will. be considered in connection with a slope of one thousandfeet in length, and a sulficient gearing is used to cause the long orfast moving hand 10 to make sixteen revolutions, while the trip orelevator is traveling a thousand feet, and the short or slow moving hand1'? making one revolution in the same distance. This movement of thehands would be the same irrespective of the distance of the slope. It istherefore apparent that when the long or fast moving hand makes onerevolution that the trip or elevator has traveled 62% feet, and duringthis movement the short or slow moving hand 17 is moved to figure 1 onthe dial. .Dividing 62%} feet by 16 indicates the distance the trip orelevator travels while the long or fast moving hand 10 moves from onefigure on the dial to the next figure. Such calculations in connectionwith the indicator allows the engineer to easily ascertain the locationof the trip or elevator in the slope. For instance, if the trip orelevator was derailed, the engineer with a few seconds thought couldtell the exact location of the trip or elevator. The alarm isprincipally used to give a signal when the trip or elevator is nearingthe tipple or top landing, the alarm being sounded approximately 100feet from the top landing so that the engineer can get the engine undercontrol. The alarm can also be used for indicating places throughout theslope where the speed of the elevator or trip is to be reduced, as whenpassing through automatic trap doors and over bad sections of track.

Vfhile in the drawings forming a part oi this application there isillustrated the preterred embodiments of my invention, I would have itunderstood that the detail construction can be varied or changed as toshape, proportion and manner of assemblage sleeve and its hand at alower speed than said first shaft, a disk on the sleeve, a pin on thedish, a stationary pawl actuated by the pin, a contact arm actuated bythe pawl, a tixed contact engagcable by the contact arm, wires connectedwith the contact arm and the fixed contact and an alarm connected to thewires.

In testimony whereof I atlix my signature in the presence of twowitnesses.
